Title: Hole cutter and plural punching machine using its
IPC: B23B47/30
Filed: 2020-04-24
Abstract: The present invention relates to a hole cutter and a multi-punching machine using the same. The hole cutter has a center shaft formed in the middle of the upper surface of a head unit of an upper portion of a rotary shaft, and punching blades formed along the outer circumferential surface of the head unit. The punching blades are cutting-edge blades and oblique blades which are oblique downwards in the rotating direction and are alternately formed at regular intervals to face each other. The multi-punching machine is constructed by using the hole cutter. Since blades cut the circumference of a hole to drill the hole, cut pieces do not remain to eliminate the task for removing cut pieces, and the cut surface of the inner circumference of the hole becomes smooth. Moreover, since only the circumference of the hole is cut, the inner circumference of the hole is prevented from cracking. The multi-punching machine by the hole cutter can smoothly drill a plurality of holes at once.
